Using this script, post decrypt we should be able to bring up the
MinIO instance with same configuration.

Sometimes IAM fails to load certain items, which could be a user,
a service account or a policy but with not enough information for
us to debug.
This commit will create a more descriptive error to make it easier to
debug in such situations.
mc admin trace -a will be able to quickly show
401 Unauthorized header to pinpoint trivial issues
between nodes, such as wrong root
credentials and skewed time.
objects/versions that are not expired via NewerNoncurrentVersions
must be properly returned to be applied under further ILM actions.
this would cause legitimately expired objects to be missed
from expiration.
this randomness is needed to avoid scanning
the same buckets across different erasure sets,
in the same order.
allow random buckets to be scanned instead
allowing a wider spread of ILM, replication
checks.
Additionally do not loop over twice to fill
the channel, fill the channel regardless of
having bucket new or old.
A new middleware function is added for admin handlers, including options
for modifying certain behaviors. This admin middleware:
- sets the handler context via reflection in the request and sends AuditLog
- checks for object API availability (skipping it if a flag is passed)
- enables gzip compression (skipping it if a flag is passed)
- enables header tracing (adding body tracing if a flag is passed)
While the new function is a middleware, due to the flags used for
conditional behavior modification, which is used in each route registration
call.
To try to ensure that no regressions are introduced, the following
changes were done mechanically mostly with `sed` and regexp:
- Remove defer logger.AuditLog in admin handlers
- Replace newContext() calls with r.Context()
- Update admin routes registration calls
Bonus: remove unused NetSpeedtestHandler
Since the new adminMiddleware function checks for object layer presence
by default, we need to pass the `noObjLayerFlag` explicitly to admin
handlers that should work even when it is not available. The following
admin handlers do not require it:
- ServerInfoHandler
- StartProfilingHandler
- DownloadProfilingHandler
- ProfileHandler
- SiteReplicationDevNull
- SiteReplicationNetPerf
- TraceHandler
For these handlers adminMiddleware does not check for the object layer
presence (disabled by passing the `noObjLayerFlag`), and for all other
handlers, the pre-check ensures that the handler is not called when the
object layer is not available - the client would get a
ErrServerNotInitialized and can retry later.
This `noObjLayerFlag` is added based on existing behavior for these
handlers only.
Add check every 2 minutes to see if a write+read operation can complete.
If disk is unresponsive for 2 minutes or returns errFaultyDisk, take it offline.
Simplify MRF queueing and add backlog handler
- Limit re-tries to 3 to avoid repeated re-queueing. Fall offs
to be re-tried when the scanner revisits this object or upon access.
- Change MRF to have each node process only its MRF entries.
- Collect MRF backlog by the node to allow for current backlog visibility
Now it would list details of all KMS instances with additional
attributes `endpoint` and `version`. In the case of k8s-based
deployment the list would consist of a single entry.

This would better to record the correct API name so that
any verification around audit logs to figure out if required
APIs are called required no of times, would be correct.
Here in this case of policy attached, API `AttachDetachPolicyBuiltin`
would be called with `requestPath` as `/minio/admin/v3/idp/builtin/policy/attach`
and in case of detach policy the value would be `/minio/admin/v3/idp/builtin/policy/detach`

Also shutdown poll add jitter, to verify if the shutdown
sequence can finish before 500ms, this reduces the overall
time taken during "restart" of the service.
Provides speedup for `mc admin service restart` during
active I/O, also ensures that systemd doesn't treat the
returned 'error' as a failure, certain configurations in
systemd can cause it to 'auto-restart' the process by-itself
which can interfere with `mc admin service restart`.
It can be observed how now restarting the service is
much snappier.
on unversioned buckets its possible that 0-byte objects
might lose quorum on flaky systems, allow them to be same
as DELETE markers. Since practically speak they have no
content.
Optimize DeleteObject API to avoid extra
GetObjectInfo call on the replicating side.
For receiving side, it is just a regular
DeleteObject call.
Bonus: Fix a corner case where version purged is
absent on target (either due to replication not yet
complete or target version already deleted in a
one-way replication or when replication was disabled).
In such cases, mark version purge complete.
Since `addCustomerHeaders` middleware was after the `httpTracer`
middleware, the request ID was not set in the http tracing context. By
reordering these middleware functions, the request ID header becomes
available. We also avoid setting the tracing context key again in
`newContext`.
Bonus: All middleware functions are renamed with a "Middleware" suffix
to avoid confusion with http Handler functions.
